As Isaiah considers his fate when before the holiness of the Lord in His temple and before His throne of judgment, it is amazing how he immediately identifies himself with the sinners, the very ones he has been denouncing in his own sermons.
"Woe is me, for I am undone! Because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts" (Isaiah 6:5).
There is not a hint of comparison in his words. In fact, the first sin Isaiah notices when before the Lord is his own. When we are before the Lord, the point is not how much sin is on you compared to the other guy. That is irrelevant. The holiness of God reveals to us the stark separation that exists between us and His holy requirements.
If your arrow falls one inch closer to the target than your neighbors, you will still here the cry, "Sin!" And that sin is enough to condemn you to an eternity of condemnation. Under such judgment, no one is comparing themselves against others.
